Answer:
20
Step-by-step explanation:
each cup cost $1.25 . if he sells 12 more cups he'll have $25
$30
You do : 22.50/0.75
because when you take off 25% you times 0.75 and 22.50 together. To undo that you divide
Answer:
Step-by-step explanation:
Our friend asking what the actual function is has a point. I completed this under the assumption that what we have is:
and used the quotient rule to find the derivative, as follows:
![f'(x)=\frac{e^{3x}(5)-[(5x-2)(3e^{3x})]}{(5x-2)^2}](https://tex.z-dn.net/?f=f%27%28x%29%3D%5Cfrac%7Be%5E%7B3x%7D%285%29-%5B%285x-2%29%283e%5E%7B3x%7D%29%5D%7D%7B%285x-2%29%5E2%7D)
and simplifying a bit:
![f'(x)=\frac{5e^{3x}-[15xe^{3x}-6e^{3x}]}{(5x-2)^2}](https://tex.z-dn.net/?f=f%27%28x%29%3D%5Cfrac%7B5e%5E%7B3x%7D-%5B15xe%5E%7B3x%7D-6e%5E%7B3x%7D%5D%7D%7B%285x-2%29%5E2%7D)
and a bit more to:
and combining like terms:
and factor out the GFC in the numerator to get:
That's the derivative simplified. If we want f'(0), we sub in 0's for the x's in there and get the value of the derivative at x = 0:
which simplifies to
which translates to
The slope of the function is 11/4 at the point (0, -1/2)
